This invention relates to a saw, and more particularly to a measuringdevice for attachment to a saw table.

The object of the invention is to provide a measuring device which canbe readily attached to a saw so that various materials such as wood orveneer, can be cut with ease and accuracy.

Another object of the invention is to provide an attachment whichincludes a rule bar that acts as a guide to permit boards and the liketo be accurately cut or sawed.

A further object of the invention is to provide a saw attachment whichis extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings, forming a part of this application, and inwhich like numerals are used to designate like parts throughout thesame:

Figure 1 is a top plan view of the saw attachment, constructed accordingto the present invention.

Figure 2 is a sectional view taken on the line 2 2 of Figure 1.

Figure 3 is a sectional view taken on the line 3--3 of Figure 1.

Figure 4.- is a plan View showing the attachment being used.

Figure 5 is a side elevational view of the saw table attachment.

Figure 6 is a bottom plan view of the attachment.

Referring in detail to the drawings, the numeral I0 designates a saWtable, broken lines Figure 3, and supported on the saw table i6 is theWood or veneer l I which is to be cut or sawed. The saw table I0 isprovided with an elongated groove or cut-out I2 of T-shape for a purposeto be later described, and the numeral I4 designates any suitable sawwhich is adapted to be used for cutting the stock II.

Movably mounted in the cut-out I2 in the saw table i is a carriage I5which includes a body member I6. The body member I8 is provided with anelongated longitudinally extending recess or groove Il in its lowersurface, and a plurality of rollers or ball bearings I8 are rotatablysupported in the groove I'I by means of pins I9. Thus the carriage l5can be shifted or moved in the cut-out I2 due to the provision or therollers I8.

Adjustably connected to the body member i6 is a rule or bar which may befabricated of any suitable material. The bar 2li is provided with scalemarkings 2| which extend along one edge thereof, and the bar 20 isfurther provided with a plurality of spaced parallel transverselyextending slots 22. An L-shaped gauge 23 is siidably mounted in each ofthe slots 22, and a set screw 24 is provided for maintaining each of thegauges 23 immobile in their adjusted positions.

A. means is provided for adjustably connecting the rule 2E) to thecarriage I5, and this means comprises threaded bolts 25 which extendupwardly from the carriage I5 through the rule Wing nuts 2S may bearranged in threaded engagement with the upper ends of the bolts 25.

In Figure 4 the rule 26 is shown being used for marking lines on a boardII so that the board can readily be cut by a saw. In this View all ofthe bolts have been removed except the two end 'bolts 25 and the boardIl is positioned or interposed between the pair of bolts 2E. rI'he rule20 can be used for marking the angular line 2 or the square marking 2E.

From the foregoing it is apparent that an attachment is provided whichWill hold a board in the exact position while being sawed. The rule bar2G acts as a guide so that the board can be accurately sawed. In thepresent invention the board is held in place and pushed through b'etweenthe saw table i and the rule 23 to be cut. Gauges 23 are constructed sothat the saw I4 is in direct alignment with the ends of the gauges sothat by putting a board that has been squared o1' angled between thecarriage i5 and the bar rule 2E), the gauges 23 can be set out or pushedout and sat on the mark for sawing and when the board is to be sawed thegauges can be pulled back. The gauges 23 may be made of any suitablematerial such as plastic, aluminum, or fiber. The screws 2'4 serve tomaintain the gauges 23 immobile in their various adjusted positions. Themarkings 2i on the rule 23 enable the operator to ascertain the width orlength of the board that is being cut or ripped. Any number of gauges 23can be used as desired. The rollers I8 insure that the carriage I5 willtravel smoothly in the groove I2 in the table I0. The two end bolts 25do not have to be removed when a board is to be inserted between therule and carriage, since the board can be merely shoved into placebetween these two members after the intermediate bolts have beenremoved. Any type of material can be handled with the present attachmentsuch as Wallboard, plaster board and the like and the groove I2 in thetable can be in any desired position in the table. The

present invention will enable the operator to accurately cut varioustypes of material. Thus, the user will be able to square or cut a boardat any angle regardless of its size or thickness. The board to besquared or eut on an angle is placed on the slide carriage l5, the boardbeing' indicated by the numeral Il and then the rule 2D is placed on topof the board ll and fastened to the carriage by the bolts 25. The wingnuts 26 can be tightened to maintain the parts immobile in theiradjusted positions.

I claim: y

An attachment for a saw 'comprising a 'carl riage slidably mounted in acut-out in a saw table and includinga body member provided with anelongated recess in itlslqtver surface, a plurality of rollers rotatablymounted in said recess for slidably supporting said carriage, a baradjustably mounted above said carriage and having indicia thereon,securing elements connecting said bar to said carriage, there being aplurality of spaced parallel slots extending transversely through saidbar, an L-shaped gauge slidably mounted in each of said slots, andsecuring elements extending through said bar and into engagement withsaid gauges.
